Abstract:
    440 Per is a Population I Cepheid with a period of 7.57d and
    low-amplitude, almost sinusoidal light and radial velocity curves.
    With no reliable data on the first harmonic, its pulsation mode
    identification remained controversial. We obtained a radial velocity
    curve of V440 Per with our new high-precision and high-throughput
    Poznan Spectroscopic Telescope.

Description:
    The PST is located in Poland at the Borowiec station, 20km south from
    Poznan city, at a meagre elevation of 123m above sea level. The PST
    consists of parallel twin 0.4-m Newton telescopes of the f ratio 4.5,
    fixed on a single parallactic fork mount. In total 158 radial velocity
    measurements of V440 Per were obtained with the PST from 2007 August
    15 to 2008 July 03.
